Closeout Gilson Opal Cabochons - Safe to Fire

Fired in carbon and made sure not to open the kiln until completely cooled. Came out great with a slight haze, but they looked great. If you cool down too quickly they crack. But, if you put a little super glue over each one after firing they will look fine.
